This is pretty much a handle to hold a standard size box cutter (X-acto knife) blade. I find that it helps apply more pressure than normal, and it is far more dangerous. If you cut your hand, it is your fault, you have been warned. Please use the sheath, as it helps resolve the cutting oneself issue stated before, and the pin can be slotted once everything has been lined up. If the pin does not want to go in, some pursuasion with a smaller, or rubber hammer can be used.

This is a work in progress and I will update with pictures showing construction, and probably not a video.

Also, printing everything at .3 mm layer height took me a total of two hours and seventeen minutes at travel speed of 60mm/s, so take from that what you will.
